- The 49ers also signed LB Brandon Chubb to their practice squad.
Bell, 25, is a former fifth-round pick by the 49ers in the 2015 NFL Draft. He is in the second year of a four-year, $2.785 million rookie contract that included a $505,132 signing bonus and is set to earn a base salary of $525,000, this year.
In 2016, Bell was active for 13 games for the 49ers and recorded four receptions for 85 yards receiving.
Dray, 29, is a former seventh-round pick of the Cardinals back in 2010. He played out his rookie contract with the team before signing a three-year deal with the Browns in 2014.
Unfortunately, Cleveland cut him loose back in February and he later caught on with the Bills. Buffalo elected to move on from Dray in October.
In 2016, Dray has been active for four games but has yet to record a statistic.
