- Bush already met with the 49ers earlier in the week.
The Lions released Bush not too long ago, and there has already been talk that he could return to the Saints.
New England is reportedly looking for a replacement to Shane Vereen, who signed with the Giants a few days ago.
Bush, 29, ran for 297 yards on 76 carries (3.9 YPC) to go along with 40 receptions for 253 yards receiving and two total touchdowns over the course of 11 games for the Lions last season.
Pro Football Focus has Bush rated as the No. 14 running back in the league last year out of 57 qualifying players.
