LSU quarterback Zach Mettenberger has a private workout this morning for the Detroit Lions along with wide receiver Kadron Boone and fullback J.C. Copeland, according to a league source.

Mettenberger also has a private workout later this month for the Tennessee Titans.

Mettenberger put on a show this week with a strong-armed throwing display during his Pro Day workout just 13 weeks removed from undergoing to repair a torn anterior cruciate ligamen in his left knee..

Mettenberger is regarded as a potential second-round draft target with some NFL analysts beginning to point toward him sneaking into the bottom of the first round.

Mettenberger has a huge arm, the biggest in the draft, and is also extremely accurate and well-coached under the tutelage of LSU offensive coordinator Cam Cameron, a former Miami Dolphins head coach who's been an offensive coordinator with the Baltimore Ravens and a head coach at Indiana.

Mettenberger a la Johnny Manziel threw in a helmet and shoulder pads and displayed an ability to plant and move around in the pocket.Mettenberger threw 125 passes, firing a large amount of intermediate throws in an unscripted workout, where he completed over 90 percent of his throws. He's expected to be 100 percent before the season begins.

"Zach threw the ball really, really well," one source who attended the workout said. "He's got the best arm in the draft. He threw a variety of passes. It was impressive."

Mettenberger had a dinner meeting Wednesday night with the Minnesota Vikings and visited the Jacksonville Jaguars on Thursday.

Boone ran a 4.44 during the Pro Day and Copeland ran a 4.94.

Boone finished his career with 44 catches for 611 yards and eight touchdowns in 51 games with 11 starts.

Last season, he caught seven passes for 129 yards and a pair of touchdowns. He worked in reserve behind standout wide receivers Odell Beckham and Jarvis Landry.

As a junior, he caught 26 passes for 348 yards and four touchdowns as he started seven of 13 games.

Boone was a high school All-American in Ocala. Fla, who caught 51 passes for 1,287 yards and 19  touchdowns as a junior with 53 catches for 931 yards and 15 touchdowns as a senior.

Copeland is a bruising lead blocker who was named the Most Valuable Player in the NFLPA Collegiate Bowl when he scored two short-yardage touchdowns.
