ENGLEWOOD, Colo. -- Denver Broncos wide receiver Wes Welker, recovering from a concussion, is on track to play Sunday night against the New England Patriots.

Welker continued to clear medical hurdles, participating in Thursday's practice on a limited basis. Barring a setback in the coming days, he should face his former team.

"I love playing the game, especially in big atmospheres like this,'' Welker said. "I'm doing everything possible on my end to get an opportunity to play in it.''

Welker progressed through the league's concussion protocol from a cognitive test Monday to limited exercise Tuesday and Wednesday. If he meets all the guidelines, he could practice fully Friday for the first time this week.
