Weak-side linebacker Erin Henderson, who missed the past two games because of a concussion, made it through the entire practice today, coach Leslie Frazier said after practice.
"We're optimistic about him playing in this ballgame," said Frazier, referring to Sunday's game against the Titans at the Metrodome. "We'll see how he does tomorrow when he wakes up to make sure he's still fine."
Frazier also added that Henderson won't step back into his role as middle linebacker in the nickel defense. Jasper Brinkley, the middle linebacker in the base defense, will continue in that role after playing it well in Henderson's absence.
Frazier said coaches will re-evaluate Henderson's role in the nickel once he's had a chance to get back up to game speed.
Meanwhile, Henderson's backup, Marvin Mitchell, strained a calf during special teams drills and will be sent for a magnetic resonance imaging exam.
If, for some reason, neither Henderson nor Mitchell can play, Frazier said either Tyrone McKenzie or rookie Audie Cole would have to start.
In other injury news:
