The Bears on Tuesday signed kicker Cairo Santos and receiver Alex Wesley, placed tight end Darion Clark on injured reserve and released receiver Trevor Davis.
Santos has converted 80.6 percent of his field-goal attempts (108-of-134) over six NFL seasons with the Chiefs (2014-17), Bears (2017), Rams (2018), Buccaneers (2018) and Titans (2019).
He made 4-of-5 field-goal tries in two games with the Bears in 2017 before sustaining a season-ending groin injury. Santos opened last season with the Titans but was released after missing all four of his field-goal attempts in a Week 5 loss to the Bills.
After Sunday's practice, coach Matt Nagy confirmed that second-year kicker Eddy Piñeiro "does have a little bit of a groin [injury] that he's dealing with right now."
Like Santos, Wesley returns for a second stint with the Bears. He spent the final two weeks of last season on their practice squad, signed a reserve/futures contract Dec. 20 and then was waived July 27.
Clark injured his shoulder in last Thursday's practice. He signed with the Bears Jan. 6. Clark was returning to football for the first time since high school after playing basketball at Charlotte (2012-13) and USC (2014-16).
Davis signed with the Bears April 29. He has appeared in 43 NFL games with four starts in four seasons with the Packers (2016-19), Raiders (2019) and Dolphins (2019), catching 16 passes for 205 yards and one touchdown. Davis also has averaged 10.1 yards on 59 punt returns and 22.4 yards on 58 kickoff returns.
