Menelik Watson re-injures calf in first Oakland Raiders practice

Menelik Watson has aggravated a calf injury during his first practice with the Oakland Raiders.

The Manchester-born offensive tackle missed the start of training camp with the leg injury, which he picked up last month.

"This is not the way I planned on my first training camp, I've not even took a snap yet. It's very frustrating, especially after the spring, making good strides in the spring. I wanted to get out there and get on the field," The AP quotes the 24-year-old as saying.

"I was aware of the situation and that I had to be careful. I talked about it with the training staff, that we were going to take it slow. You get out there and you get your juices flowing and you're trying to push it, and it happened."

The Raiders are optimistic that the second-round draft pick will be able to return to practice next week.
