Alexander, 25, is a former fourth-round pick of the Buccaneers back in 2015. He played out the final year of his four-year, $2,758,320 contract before agreeing to a four-year contract worth $54 million with the 49ers this offseason. 

This will be the second straight year Alexander has finished on injured reserve, as in addition to his torn pectoral this year he suffered a torn ACL in 2018.

In 2019, Alexander appeared in eight games for the 49ers and recorded 34 tackles, a half sack, an interception, a forced fumble and four pass defenses.

Celek, 31, wound up signing on with the 49ers as an undrafted free agent out of Michigan State back in 2012. After playing out his rookie contract, Celek returned to San Francisco on a one-year deal and later signed a four-year, $14 million extension in 2016.

In 2018, Celek appeared in 15 games for the 49ers and recorded five receptions for 90 yards receiving and two touchdowns.
