Westbrook (knee) was a full participant in practice Wednesday and said he will "most definitely" be ready the Vikings' Week 1 matchup with the Bengals, Chris Tomasson of the St. Paul Pioneer Press reports.

Westbrook looks to be all the way back from a torn ACL suffered Week 7 of last season. It's not clear what kind of role he'll have against the Bengals. On the heels of a solid preseason, K.J. Osborn heads into Week 1 as the Vikings' No. 3 receiver, but Westbrook could eventually usurp him for those duties.
