As TCU closes out their 2015 regular season campaign against Oklahoma (9-1) and Baylor (8-1), they’ll have to do so without wide receiver Josh Doctson.

Head coach Gary Patterson announced after practice Wednesday that Doctson, TCU’s single season receptions leader, is done for the regular season with the possibility of a return come bowl season.

Patterson also said quarterback Trevone Boykin is a “maybe” for Saturday’s contest in Norman.

Boykin and Doctson join a long list of injuries TCU has endured since fall camp began in August.

Since fall camp, over 20 TCU players have been sidelined for injuries. Most of which have starting experience.

“In 33 years, I’ve never had it like this,” Patterson said after practice Wednesday.

The Frogs have now had 43 different players start at some point this year.

TCU, a 45-point favorite heading into the Kansas game,  found themselves tied with the Jayhawks at halftime Saturday before rallying to a 23-17 win.

“As the game went on, they became more emotional. Had to overcome Trevone and Doc not being in a whole lot. So we’ll be more prepared for that situation this week,” Patterson said.

Despite a tremendous volume of injuries, TCU defensive tackle Terrell Lathan said the team maintains a “next man up” approach after a close game against Kansas.

“Everybody’s a starter, basically,” Lathan said. “If somebody gets hurt, the next man has to step up.” At quarterback, the next man up will likely be redshirt freshman Foster Sawyer, Patterson said. Sawyer currently has the edge over senior Bram Kohlhausen who initially replaced Boykin against Kansas. Kohlhausen completed 13 of 19 passes for 112 yards before being replaced by Sawyer. Sawyer completed just one of seven passes, but he did connect with Shaun Nixon for a 42 yard touchdown pass. If Boykin can’t play at Oklahoma, the Frogs may rely on the running game, just as running back Aaron Green said they did last Saturday. Green rushed for 177 yards on 30 carries. “You know we have inexperienced people out there throwing the ball,” Green said of Sawyer and Kohlhausen. “I know I had a career high in carries and it’s just what we have to do to win.” Green said it was difficult for the offense to adjust to new quarterbacks mid-game with limited practice:
