The Browns placed linebacker Christian Kirksey and cornerback E.J. Gaines on injured reserve Wednesday, ending the 2018 season for both of the starters.

Kirksey suffered a hamstring injury in the second quarter of Sunday’s 37-21 loss to the Kansas City Chiefs.

"I keep my head up cause I’m blessed! Gods plan. Thank you Cleveland, til next year," Kirksey wrote on Instagram.

Gaines suffered a concussion in the first quarter against the Chiefs. He also missed the previous two games with a concussion.

Starting middle linebacker Joe Schobert returned to practice Wednesday after missing three games with a hamstring injury. Starting free safety/cornerback Damarious Randall (groin) and undrafted rookie left tackle Desmond Harrison (illness) came back to practice after sitting out against the Chiefs.

Starting cornerback and rookie No. 4 overall draft pick Denzel Ward (hip), starting linebacker Jamie Collins (undisclosed) and starting center JC Tretter (ankle) didn't practice Wednesday. Ward and Collins worked out beside the field on stationary bikes. 

The Browns also signed defensive back Juston Burris off the New York Jets’ practice squad. They signed defensive back Arrion Springs to the practice squad and released offensive lineman Jake Eldrenkamp from the practice squad.

Kirksey, who was voted a captain by his teammates, started seven games this year and compiled 43 tackles, two interceptions and one fumble recovery. Kirksey, 26, is under contract with the Browns through the 2021 season after signing a four-year, $38 million contract extension last year.

Gaines, on the other hand, could very well have played his final game with the Browns. Gaines, 26, joined them by signing a one-year, $4 million contract in the offseason and is scheduled to become an unrestricted free agent in March. He appeared in six games with two starts this season and tallied 12 tackles, three passes defensed and one interception.
