NFL Draft Diamonds reports that the Texans also worked out LS Christian Kuntz on Saturday.
DePaola, 33, wound up signing on with the Buccaneers as an undrafted free agent out Rutgers back in 2012. He spent over five years in Tampa Bay before the Buccaneers waived him at the start of the 2017 season and he was later claimed off of waivers by the Bears.
The Raiders signed DePaola to a four-year, $4.27 million contract in 2018, but was eventually placed on injured reserve and released after one season. The Panthers signed him to a contract last offseason.
In 2017, DePaola appeared in all 16 games for the Bears and recorded one tackle.
