From high-profile additions to NFL journeymen, The Bee provides a primer to the new players jockeying for position in training camp. Get to know the new faces at two position groups each day for both the 49ers and Raiders. Rosters are cut to 75 players Sept. 1 and 53 players Sept. 5. Read Matt Barrows’ in-depth position preview here.

The 49ers said goodbye to their franchise rushing leader when Frank Gore, a 10-year veteran who played his whole career with San Francisco, left for Indianapolis.

Reggie Bush comes over from Detroit and should be a nice asset on screens and swing passes, but there are five other running backs currently on the roster, including two returners.

Key returners: Kendall Hunter, Carlos Hyde

Key departures: Frank Gore (Indianapolis), LaMichael James (Miami), Marcus Lattimore (retired)

The newcomers

Reggie Bush | 6-foot | 205 pounds

Experience: Nine years (USC)

Last year: Bush played in 11 games with the Detroit Lions, rushing for 297 yards and two touchdowns, along with recording 40 receptions for 253 yards.

The skinny: Bush, the No. 2 overall pick in the 2006 draft, was known for his versatility at USC and won the Heisman Trophy in 2005, an award he’d later surrender after the school was punished over rules violations. He’s only rushed for more than 1,000 yards twice in his NFL career but remains a receiving threat, as he’s logged at least 34 catches each season, including 88 as a rookie. Durability is an issue, though, as he’s played all 16 games just twice. Casual fans might know Bush for a reason not related to sports: He once dated popular reality star Kim Kardashian.

Mike Davis | 5-foot-9 | 217 pounds

Experience: Rookie (South Carolina)

Last year: The junior ran for 982 yards and nine touchdowns, and had 32 receptions for 368 and two scores for the Gamecocks.

The skinny: The 49ers selected Davis in the fourth round of the 2015 draft. calls Davis a “rhythm runner who is at his best when he’s getting plenty of work. Davis has a surprising ability to turn on the jets and get on top of the secondary quickly for long runs, and his north-south mentality is a fit for the pros.”

Kendall Gaskins | 6-foot-1 | 238 pounds

Experience: Rookie (Richmond)

Last year: Gaskins was signed to the 49ers’ practice squad on Sept. 1, 2014.

The skinny: Gaskins, who has not played a down in the NFL, signed with Buffalo in 2013 after going undrafted, then signed a future/reserve deal with the New York Giants before coming to San Francisco. He played four collegiate seasons with the Spiders, scoring 38 total touchdowns, including 16 (13 rushing, three receiving) as a senior.

Jarryd Hayne | 6-foot-2 | 220 pounds

Experience: Rookie

Last year: Hayne is a former rugby star in his native Australia. He was twice honored for being the National Rugby League’s best player (2009, ’14).

The skinny: Hayne is adjusting to playing a new sport, but 49ers coach Jim Tomsula told The Bee he’s “thrilled” to have Hayne on the roster.
