The San Francisco 49ers have officially expanded their roster by signing Sincere McCormick and Patrick McMorris to one-year contracts. McCormick, a running back with previous experience across several NFL practice squads, returns to the team after a collegiate career at UTSA where he earned multiple offensive honors. Joining him is McMorris, a young safety who originally entered the league as a Miami Dolphins draft pick after playing at San Diego State and California. Both players are looking to solidify their roles on the team following various stints with other professional organizations. These roster moves occurred alongside a broader series of front office activities and coaching staff updates following the 2026 NFL Draft.
