Minnesota Vikings linebacker Erin Henderson and safety Mistral Raymond are still not cleared to return to action, according to Judd Zulgad of 1500ESPN.com.
Henderson suffered a concussion in Week 2 against the Indianapolis Colts, and hasn't seen the field since. When he eventually returns, Henderson could lose nickel package reps to Jasper Brinkley.
Meanwhile, Raymond partially dislocated his ankle in the Vikings' 24-13 win over the San Francisco 49ers the following week. However, his job should be safe when he comes back in a few weeks, although Jamarca Sanford has played well in Raymond's place.
Henderson, who was signed by the Vikings as an undrafted free agent out of Maryland in 2008, has yet to play a full season in the NFL. His best year came in 2011, when he racked up 70 tackles and 1.5 sacks in 15 games.
Raymond, in his second year out of South Florida, accumulated 22 tackles and an interception in 10 games as a rookie in 2011.
