GLENDALE, Ariz. -- Arizona Cardinals rookie running back T.J. Logan will undergo surgery to repair a dislocated wrist and will be placed on injured reserve.
The fifth-round pick out of North Carolina was injured during Thursday night's Hall of Fame Game against the Dallas Cowboys. He will miss at least 12 weeks.
Coach Bruce Arians said the team would like to activate Logan off injured reserve when he is eligible. That would be at or around Week 8 of the regular season.
The injury is a big blow to the Cardinals, as Arians said he saw enough in just one exhibition game from Logan to be ready to declare the rookie as his primary kickoff and punt returner. Logan returned two kicks for 71 yards against Dallas, including one he broke for a 43-yard gain. He also returned one punt for 10 yards and rushed four times for a team-high 24 yards.
"It's a blow to him. He was just about to make a nice role for himself," Arians said. "He obviously looked electric on the kick returns and the punt returns, so somebody else is just going to have to step up and do it."
Arians said the top four options for kickoff-return duty are running back Kerwynn Williams, receiver John Brown -- when he is healthy enough to return from a quad injury and resume practicing -- rookie receiver Chad Williams and rookie defensive back Rudy Ford.
Logan's absence will also be felt in the running backs room, where there is now competition between five players for the final three spots behind starter David Johnson.
"Nobody's really got a hand (up) other than David," Arians said.
Asked if that meant not even veteran Chris Johnson is guaranteed a spot, the coach replied, "Yeah, sure. Nothing's guaranteed."
Aside from Chris Johnson, others in the mix at running back include Kerwynn Williams, Andre Ellington, Elijhaa Penny and rookie James Summers. Both Penny and Summers are eligible for the practice squad.
"You never want to see a teammate go down like that, especially someone who was playing as well as he was," Kerwynn Williams said of Logan. "Seeing him go down like that when he was playing so hard, it's always tough."
So will be the competition for the final roster spots at the position, David Johnson said.
"All I know is that it's going to be tough. It's going to be tough choices," he said. "All the running backs are good. I don't know how many they're going to keep -- who knows? -- but I know it's probably going to be the hardest choice to make cuts at any position just because all our backs are so good."
"Oh yeah, it's going to be real tough because everybody's explosive. They all pass-block well. They can catch. It's going to be who stays healthy."
