CJ West, Deebo Samuel to return to 49ers practice; Mike Evans remains out

Despite a season-ending injury to promising rookie defensive tackle Gracen Halton, general manager John Lynch and the 49ers decided not to bolster their defensive front at Tuesday s NFL trade deadline.  With the addition of DeForest Buckner one week before, Lynch explained in an interview with KNBR s Murph and Markus Thursday that he s confident with San Francisco s defensive line as it is currently constructed and opted not to make any deals to add to the position group. If you ve seen our history, I think that s always a spot you can t have enough good D-linemen, Lynch told Brian Murphy and Markus Boucher. Now you do have a 53-man roster, too, and so, there s only so much you can do. But, we did make some calls. We inquired, but we really like our group.   Lynch noted Buckner, Osa Odhigizuwa, Nick Bosa, rookie Romello Height, Keion White, Mykel Williams and CJ West as key players on the defensive line. The 49ers have focused on bolstering the group through the draft,
