The 49ers had one of the most loaded rosters in the NFL before the draft. Then they added 12 drafts picks during it. That means they don't have a lot of room for undrafted free agents, though they are starting to fill up those slots.
* QB Kory Faulkner, Southern Illinois, 6-3, 229
Faulkner is a big, strong-armed quarterback who threw 18 touchdowns against four interceptions last year. He missed three games with a broken finger but still finished with 1,997 yards and averaged nearly 222 passing yards a game. Faulkner also can run. He rushed 60 times for 283 yards and scored two rushing touchdowns last year. Jim Harbaugh met with Faulkner during his trip to Miami, Ohio for the recent unveiling of his brother's statue on campus. He said Faulker has experience in a read-option offense and also has operated under center. He'll compete against Blaine Gabbert and McLeod Bethel-Thompson for a backup job this offseason.
* OLB Morgan Breslin, USC, 6-1, 240
The junior college transfer had a team-high 13 sacks last year but suffered a hip injury that limited him to just four sacks his senior year in 2013. He had a good showing at the Trojans' pro day in March, leaping 35 1/2 inches in the vertical jump and pumping out 26 repetitions of 225 pounds in the bench press.
* TE Asante Cleveland, Miami, 6-5, 261
Sacramento product (Christian Brothers) has great size but was underutilized by the Hurricanes. He only caught three passes as a senior last year.
* C Dillon Farrell, New Mexico, 6-4, 303
All-Mountain West honorable mention has good size and experience at both guard and center.
* OT Fou Fonoti, Michigan State, 6-4, 308
Fonoti has played in 28 career games with the Spartans, and he started all 12 contests as a senior. He started the last nine games at right tackle.
* S L.J. McCray, Catawba, 6-0, 215.
McCray is a very athletic safety who stood out with an impressive 41-inch vertical leap at his pro day. His best fit immediately might be on special teams coverage units. The 49ers' top players there -- C.J. Spillman, Bubba Ventrone, Dan Skuta and Kassim Osgood -- are entering the final year of their contracts. McCray also has returned kicks.
* ILB Shayne Skov, Stanford, 6-2, 245
Skov, of course, is familiar to Harbaugh and defensive coordinator Vic Fangio who coached him at Stanford. Skov had a fantastic season in 2010 but suffered an ACL injury the following year. He rebounded this past season and was a finalist for the Butkus Award. He recorded a team-high 109 tackles (62 solo), 13 tackles for loss and 5 1/2 sacks.
