Bills' Stevie Johnson limited in practice

ORCHARD PARK, N.Y. -- Buffalo's Stevie Johnson has returned to practice on a limited basis, though coach Chan Gailey says it's too early to determine whether the leading receiver's injured left shoulder will be healed in time to play at Miami on Sunday.

Gailey provided the update after practice Thursday, while also noting slot receiver David Nelson missed a second straight practice, this time due to an illness. Gailey says Nelson's sore ankle is feeling better and adds he would've practice had he not fallen sick.

Johnson hurt his shoulder in a 44-7 loss at Dallas last weekend.

Starting safety George Wilson missed a second day of practice since hurting his neck against Dallas. Gailey says it's "questionable" whether Wilson will play against Miami (2-7).

The Bills (5-4) have lost three of four.
