49ers are working out four wide receivers today

Brandon Aiyuk sat out of Tuesday’s practice with a hamstring injury. The 49ers have been hit hard at receiver, and Ian Rapoport reported that the team is hosting four wide receivers on Tuesday:

— Ex-Raiders & Steelers WR Johnny Holton.

— Former Bears 1st rounder Kevin White.

— Former Bengals WR River Cracraft.

— Former Falcons WR Justin Hardy.

Holton spent the first three seasons of his career in Oakland and 2019 with the Steelers. Holton has 14 catches for 273 yards and three touchdowns in his career. At his Pro Day, Holton ran a 4.4 40-yard dash and had a 36.5-inch vertical. His 3-cone was 6.9, and his 10-yard split was 1.51. All of those are impressive numbers, especially for a 6’3” receiver.

White is the most notable name as he was a high draft pick. He has a brutal injury history that includes two leg fractures and a shoulder fracture. White has never played more than nine games in a season. White has 25 receptions in his career for 285 yards.

I can confidently say that I’ve never heard of Cracraft. He’s 25 and spent a brief time with the Broncos and the Eagles, who waived Cracraft in April. The Southern California native was cut and re-signed by Denver multiple times and was ultimately promoted to the active roster in November 2018, returning a punt for 5 yards in his debut against the Houston Texans. Cracraft caught his first pass, a 44-yard reception, in the Broncos’ regular-season finale against the Los Angeles Chargers.

Hardy played with Kyle Shanahan in Atlanta in 2016. Hardy had 19 receptions for 195 yards in 2019. In his career, Hardy has 95 receptions for 946 yards and nine touchdowns. He’s 28.
