Giants WR Colin Johnson tears running back Sterling Shepard’s Achilles

The Giants lost their starting-caliber wide receiver to injury the same day they brought him back.

Colin Johnson tore his right Achilles during practice on Tuesday, the same day Sterling Shepard made his training camp debut.

Johnson, 24, was a standout in Giants camp. He earned regular first-team reps, and his 6-foot-6 frame gave the offense a high-functioning big receiver target with Kenny Golladay off to a slow start.

“The guys that have been there and are producing — guys like Collin Johnson and David Sills — they’ve stepped up and fit in not only to make the team, but to play,” head coach Brian Daboll said Monday. .

The Giants’ projected Week 1 starters at receiver appear to be Shepard, Golladay and second-round pick Van’Dale Robinson.

Sills qualifies for a bigger role. Kadarius Toney continues to spend more time on one knee than on two legs in practice.

His right hamstring seemed to bother him Tuesday during his only work in the individual. He was unable to practice fully in 10 of the team’s 17 practices this summer.

Darius Slayton continues to work on the sideline after straining in the Giants’ preseason game in New England. He projects as the end of the camp. It’s unclear if injuries to other players could change that.

The Giants also claimed receiver Jaylon Moore off waivers from the Baltimore Ravens on Tuesday.

The 6-2, 190-pound Moore, 25, spent the past two seasons on the Ravens’ practice squad. He had a good camp in Baltimore, but was quiet in two preseason games.

At least Shepard, 29, is back after coming off the physically disabled list.

The veteran Giant has a good relationship with Jones, having played together for three seasons. He looked strong Tuesday in his first practice since tearing his left Achilles on Dec. 19.

On Tuesday, he ran with Jones’ offense on the first chain and caught a pass from backup QB Tyrod Taylor on the left side.

“I felt great, man, just getting back on the field,” Shepard said after practice.

Shepard took a pay cut this offseason under a restructured contract to remain with the team. It’s good that he did.

They need him.
