JACKSONVILLE, Fla. -- Jaguars quarterback Trevor Lawrence suffered a right ankle injury late in the fourth quarter of Monday night's overtime loss to the Cincinnati Bengals and did not return.

Initial tests showed that Lawrence sprained the ankle, sources told ESPN's Adam Schefter. He is scheduled to undergo additional testing to determine the extent of the injury.

Jaguars coach Doug Peterson did not have an update on Lawrence's status after the game.

Lawrence was hurt when left tackle Walker Little was pushed backward and stepped on his ankle, which then appeared to get caught underneath him when he fell to the ground. Lawrence tried to get up, then went down to his knees and slammed his helmet on the ground in frustration.

Lawrence was assisted from the field by medical personnel and needed the help of a person underneath each arm while he was walking in the tunnel toward the Jaguars' locker room and X-ray area.

Backup quarterback C.J. Beathard took over on Jacksonville's next offensive possession with 2:28 left in the fourth quarter. He led the Jaguars to a game-tying field goal to send the game to overtime, where they lost 34-31.

The Jaguars also lost receiver Christian Kirk to a groin injury earlier in Monday's game.

Kirk was hurt when he made a 26-yard catch on the Jaguars' first offensive play. He hit the ground hard and after being down for several moments was assisted off the field. He was taken straight into the locker room.

Kirk entered the game as the Jaguars' receiving yards leader (761) and second in receptions (56).

Nickelback Tre Herndon also was ruled out with a concussion.
