Chris Cooley and Chris Samuels could be placed on injured reserve this week, Jim Zorn said on Monday.
Cooley suffered a chip fracture in his ankle in the second quarter of Monday night's 27-17 loss to the Philadelphia Eagles.
"Chris is looking at a final evaluation from another doctor to determine if in fact he needs surgery," Zorn said. "The minimum is 6-8 weeks that he'll be out. We're probably going to put him on injured reserve. It hasn't been decided yet about surgery or not.
"It's going to be a long healing for him. He thinks he heals fast--and he probably does. I don't think I can hold the roster spot open. So we'll be looking for another tight end to come in and help us out."
Zorn called the loss of Cooley "devastating."
"He is such a good player for us all over the field," Zorn said. "He is good for our football team. Much like Chris Samuels, he just wants to be around and he is going to want to be involved in what he can. But the loss of him on the field and his fight that he brings to the field--it's going to be a big loss."
Fred Davis replaced Cooley in the lineup. Davis caught a career-high eight passes for 73 yards and a touchdown.
Samuels remains sidelined with a neck injury suffered in the Oct. 11 game at Carolina.
He issued a statement last week saying that he continues to seek medical advice about his neck injury. He was diagnosed with spinal stenosis during high school but was able to play for many years with the condition.
He has not yet made a decision about his long-term future in the NFL.
Stephon Heyer, Samuels' replacement at left tackle, suffered a knee ligament injury in the Eagles game
"He's in a brace," Zorn said. "I'm hoping he'll be fine by the next game [at Atlanta on Nov. 8]. He has some time."
The Redskins suffered a myriad of injuries, bumps and bruises in the Eagles game.
H.B. Blades and Byron Westbrook left the game in the first half with knee injuries.
On Tuesday, Westbrook was walking with crutches as he entered Redskins Park.
"We're trying to evaluate both injuries and we'll decide what to do based on the findings," Zorn said. "Right now it looks like [Blades] is going to be out for a game at least."
Jason Campbell suffered a sprained ankle, but he was able to finish the game.
Zorn acknowledged that Campbell may have been limited in his ability to scramble. He was sacked six times in the 27-17 loss.
Albert Haynesworth, Clinton Portis and Mike Sellers also have sprained ankles. They were each able to finish the game.
