Center Trystan Colon-Castillo and linebacker Kristian Welch have signed their exclusive rights tenders, according to the Ravens’ official Twitter account.
Colon-Castillo was signed as an undrafted free agent last offseason, and he started two games at center last season. He did not allow a sack and earned an overall PFF grade of 67.6. He gives the Ravens some solid depth at center. Meanwhile, Patrick Mekari is still under contract, and Greg Mancz was signed to a reserve/future contract in January. Additionally, guard Bradley Bozeman is capable of playing center.
Welch was also signed as an undrafted free agent.
