Lee was carted off the field in the first quarter after Falcons cornerback Damontae Kazee twisted his leg making a tackle. Lee fumbled on the play, but it was overturned because Kazee was flagged for tackling with his helmet.
Teammates and coaches offered well-wishes to Lee as he left the field. Nonetheless, it was the kind of preseason injury that leaves players, coaches and fans shaking their heads.
It also reaffirmed Falcons coach Dan Quinn's decision to rest two of his biggest offensive stars, receiver Julio Jones and running back Devonta Freeman.
Lee had 56 catches for 702 yards and three touchdowns last season. He signed a four-year, $34 million contract in March that included $16.5 million guaranteed.
A second-round draft pick from USC in 2014, Lee has 171 catches for 2,166 yards and eight touchdowns. He missed games because of various injuries in three of his four seasons.

BEARS 27, CHIEFS 20
CHICAGO (AP) 鈥?Bears coach Matt Nagy decided to rest starters for the next-to-last preseason game rather than use it as the customary regular-season tuneup.
And the backups proved that they're also ready for the regular season as Chase Daniel directed touchdown drives on the first three possessions.
The Bears played in the Hall of Fame Game and have been practicing since July 20, and Nagy liked what he'd seen from the starters in practices. So he decided Friday to keep starters out of what normally would be a dress rehearsal for the regular-season opener at Green Bay.
Daniel replaced Mitchell Trubisky against his mentor, Andy Reid, and the Chiefs, the team Nagy last year served as the offensive coordinator.
Playing against both the Chiefs' starting defense and then the backups, Daniel led the Bears to a 24-10 halftime lead. Daniel
RAMS 21, TEXANS 20
LOS ANGELES (AP) 鈥?Rookie John Kelly rushed for 64 yards and two touchdowns, and the briefly debuted their new defensive stars.
Although the Rams rested 10 presumptive offensive starters for the third straight preseason game, the Los Angeles defense's three big offseason acquisitions played at the Coliseum. Ndamukong Suh and cornerbacks Marcus Peters and Aqib Talib got some action early in the first quarter before sitting.
J.J. Watt also started and made a tackle in his first on-field action since breaking his leg in the Texans' fifth game last season. The three-time NFL Defensive Player of the Year didn't get to see the current holder of the award, Aaron Donald, who is deep in his second consecutive contract holdout from the Rams.
Alfred Blue rushed for an early score for Houston, and Braxton Miller caught a TD pass from Brandon Weeden
Nick Rose then missed a 57-yard field goal at the gun.
STEELERS 16, TITANS 6
PITTSBURGH (AP) 鈥?Ben Roethlisberger made the most of his brief preseason cameo, throwing for 114 yards and a touchdown.
New Pittsburgh offensive coordinator Randy Fichtner didn't let Roethlisberger's lone scheduled exhibition appearance ahead of the Sept. 9 season opener at Cleveland go to waste. Roethlisberger completed 11 of 18 passes during his three drives, including a 32-yard rainbow to Justin Hunter for a score late in the first quarter.
Titans quarterback Marcus Mariota, meanwhile, struggled against Pittsburgh's starting defense. Mariota completed 5 of 8 passes for 43 yards while playing most of the first half. He missed a wide-open Corey Davis for what would have been a long touchdown on Tennessee's opening drive and his afternoon ended late in the second quarter when Steelers rookie safety Terrell Edmunds picked off a floater intended for Taywan Taylor.
The Titans didn't do much in the run game to take any of the pressure off Mariota. Derrick Henry and Dion Lewis combined for 23 yards rushing on eight carries. Tennessee's lone touchdown came on a 3-yard touchdown pass from Blaine Gabbert to tight end Anthony Firkser in the fourth quarter.
COLTS 23, 49ERS 17
INDIANAPOLIS (AP) 鈥?Andrew Luck threw a touchdown pass on what will probably be his last preseason drive, and Christine Michael scored on a 1-yard plunge late in the third quarter.
Luck looked much sharper than he did in Monday night's loss to Baltimore. He wound up 8 of 10 with 90 yards and produced the only TD in the first half. He also had four carries for 27 yards before leaving midway through the second quarter.
Alfred Morris carried 13 times for 71 yards in the first half as San Francisco piled up 99 yards on the ground. Morris finished with 17 carries for 84 yards.
Still, the Colts managed to keep the 49ers out of the end zone until late in the fourth quarter and nearly picked off Jimmy Garoppolo on back-to-back plays near the goal line late in the first half. Garoppolo was 9 of 19 with 135 yards before giving way to C.J. Beathard midway through the third quarter.
The New York Jets have released kicker Cairo Santos, a day after claiming Jason Myers off waivers from Seattle.
The team signed free agent cornerback Darrelle Revis to the active roster with its corresponding move Wednesday.
No, the seven-time All-Pro is not returning. The one-day contract he signed last month to retire as a member of the Jets was officially submitted since New York had a spot on its 90-man roster.
Santos signed with the Jets in March, but was unable to kick in training camp because of a groin injury suffered late last season while with Chicago. Coach Todd Bowles says New York could add another kicker to compete with Myers and Taylor Bertolet.
Wide receiver Jonah Trinnaman, who was waived-injured Tuesday, was unclaimed and reverted to the Jets' injured reserve list. He doesn't count against the 90-man roster.
