Lions QB Matthew Stafford ‘not 100 percent’ after knee injury

The Detroit Lions quarterback Matthew Stafford has been ruled out for the remainder of the season with a right knee injury, the team announced Wednesday.

The team announced the news during Lions minicamp.

Stafford was injured in the second quarter of Sunday’s game against the Minnesota Vikings.

He was carted off the field on crutches, according to NFL Network’s Mike Garafolo.

Lions coach Jim Caldwell said Stafford is expected to miss the next several weeks.

Stafford, 25, threw two touchdowns and two interceptions during the Lions’ 34-28 loss.

He has a 3-9 record, including a 6-10 mark against the Vikings.

“It’s been a little bit of a setback to get to this point in the season, to be honest with you,” Caldwell said.

“He’s not 100 percent.

He’s not playing as well as he did at this point last year.

He doesn’t feel 100 percent yet.”

Caldwell said the Lions “have to do a little more to get the ball back to Matthew as fast as possible.”

Stafford was in full pads and on cradles during minicamps this offseason and he threw a few passes during that time.

Stafford is one of four quarterbacks on the roster with no games played.

The Lions had been planning to rest Stafford for at least a month.

He will likely be placed on the physically unable to perform list and will likely miss the start of the regular season.

The injury occurred during a Lions offensive series against the St. Louis Rams, who were without running back Jeremy Langford.

Lions WR Calvin Johnson returned to practice Tuesday after missing the previous three games with a hamstring injury.

Johnson was not on the field for the second half of the Lions season opener.

He did not practice Wednesday.

Johnson will be the first player to miss at least the first two games of the 2017 season with an injury.

Lions wide receiver Brandon Pettigrew missed his second straight game with a knee injury.

The 6-foot-3, 205-pound Pettigreek was listed as questionable Wednesday.

Stafford missed his first four games with an ankle injury.

He injured his right ankle and will undergo a physical.
