In a press conference this week, head coach Mike Shanahan explained his reasoning for deactivating Mike Sellers in last Sunday's game against the New York Giants.
"You have to deactivate seven players and it's really tough sometimes," Shanahan said. "You have to take a look at the tight end situation, your fullback situation. We had three tight ends that played, Chris Cooley was up, Darrel Young [was active] and five wide receivers were up. You have to take a look at the flexibility of your team.
"The thing that's great about Mike is that he can play both the tight end and fullback position. He can help on special teams. Usually the decision we make is if a guy is first or second team, he has the chance to be up.
"Then, there is the wild card on special teams. Sometimes it may be [Brandon] Banks, sometimes it may be Sellers or maybe it's another player. Sometimes it's [because of an] injury."
Shanahan did not say if Sellers would be deactivated again, but he did expect him to have an impact in some way on the football team.
"Mike Sellers will play a lot for us," Shanahan said. "Mike is exactly the type of guy you want on a football team. He will do everything possible he can to get ready on game day whether he's playing tight end or fullback and he's going to play special teams.
"When he doesn't play, he's still supporting his teammates. A lot of guys aren't smart enough mentally to take that. He is a winner and he's going to help the football team if he's on the football field or not."
