Petersen made a Football Championship Subdivision-record 44 quarterback sacks in his four seasons with the Toreros, which concluded in 2017.
The 6-foot-1-inch, 240-pound Petersen is the only USD football player to be a four-time first-team All-American selection.
Other signings announced Thursday included running back Terrell Watson and receiver Nelson Spruce
Spruce was undrafted out of Colorado but survived the Los Angeles Rams final cut in 2016. He was inactive the first nine weeks of the season and then placed on injured reserve. He has not played in an NFL game.
The other signings announced Thursday were linebacker Al-Rasheed Benton, receivers Wayne Capers, Jevon Floyd, Jordon Gandy, LaQuvionte Gonzalez and Gary McKnight; defensive tackles Derrick Dixon, Jose Duncan, Michael Hill, Andrew Stelter and Aniela Tupou; defensive backs Marvin Gross, Tyree Holder and Justin Williams; running back Paul James; and guard Jerron Searles.
The signings increase San Diego’s roster to 49 players.
The league is set to begin play Feb. 9.
