Hayne, 27, signed a three-year contract that included $115,100 guaranteed with the 49ers back in March. However, he was waived back in October before later being signed to the team’s practice squad after clearing waivers.
It seems likely that the 49ers will offer him a reserve/future contract after the season has concluded, which will give him another shot at competing for a roster spot next summer.
This season, he’s appeared in six games and ran for 25 yards on eight carries (3.1 YPC) to go along with one reception for seven yards receiving. He has also contributed 76 kick return yards.
Boone, 28, is in the final year of his five-year, $7.450 million contract that included $2.24 million guaranteed. He stands to make a base salary of $3.4 million this season before becoming an unrestricted free agent next March.
His 2015 season ends with him appearing in 13 games for the 49ers. Pro Football Focus has him rated as the No. 33 guard out of 82 qualifying players.
