‘Coach Mike Mularkey said after practice Tuesday that he’s leaning toward starting Holcomb even though Losman practiced on a limited basis. Losman sat out Buffalo’s 28-17 loss to Denver last weekend after hurting his throwing shoulder and left leg in a loss to New England on Dec. 11. Losman, who is listed as probable to play, showed no signs of difficulty throwing passes in practice, but did walk with a slight limp.’
