General manager Reggie McKenzie also formally announced Thursday that the team signed free agent kick returner and wide receiver Josh Cribbs.
McGloin set a Penn State record with 46 career touchdown passes. He also set single-season program marks in 2012 for completions (270) and yards passing (3,266), and tied the season record in touchdown passes (24).
The Raiders waived linebacker Jerrell Harris and long snapper Nick Guess to make room on the roster.
The signing Thursday comes two days after outside linebacker Melvin Ingram tore the anterior cruciate ligament in his left knee, putting his season in jeopardy.
The Chargers also are wooing free agent Dwight Freeney.
Keiser spent his first two seasons with the Panthers after joining them as an undrafted rookie from Stanford in 2011. He started his rookie season on the practice squad and was signed to the active roster for the final eight games in which he totaled four sacks, an interception and nine tackles. Last year, Keiser played in four games before being placed on injured reserve with a damaged left elbow.
