Succop previously spent time on the PUP list during camp with a knee injury, but had been activated and was supposedly trending toward playing. This move shelves him until at least Week 9.
Succop, 32, is a former seventh-round pick of the Chiefs back in 2009. He played five seasons in Kansas City before joining the Titans for the 2014 season.
Succop finished out his contract before agreeing to a five-year, $20 million contract with the Titans that includes $7.25 million guaranteed last year.
In 2018, Succop appeared in all 16 games for the Titans and converted 26 of 30 field goal attempts (86.7 percent) to go along with 28 of 31 extra point tries.
Santos, 27, wound up signing on with the Chiefs as an undrafted free agent out of Tulane back in 2014. He returned to the Chiefs on a one-year restricted deal worth $1.797 million.
Kansas City elected to place him on injured reserve with a groin strain at the start of the season and cut him loose with a settlement soon after. The Bears later signed him to a contract before placing him on injured reserve for the second time during the 2017 season.
The Jets signed Santos to a contract in 2018 but released him during the preseason. He later caught on with the Rams but he lasted just a few weeks in L.A. before signing with the Buccaneers and finishing out the year in Tampa Bay.
Santos re-signed with the Buccaneers for 2019, but lost the kicking competition to rookie Matt Gay and was released coming out of the preseason.
In 2018, Santos appeared in two games for the Rams and nine games for the Buccaneers, converting 14 of 18 field goal attempts and 22 of 23 extra point tries.
