Browns receiver David Nelson signed as a free agent in April coming off a torn anterior cruciate ligament admitted Thursday night that he's worried about Saturday's final cuts.

"I think you have to be'' he said. "I don't think anybody's safe and the fact I haven't played the first three preseason games I wasn't able to show anything in OTAs and I wasn't able to show anything in preseason. All I have to show is a week and a half of practice and the game I just put out there.''

Nelson was unhappy with his performance despite it was first game action since he tore the ACL in the opener last September as a member of the Bills. He caught only four of the 10 passes thrown to him by Brian Hoyer slipped twice dropped one and had one intended for him picked off.

"I feel like every time the ball's in my area I should come down with it'' said Nelson who missed most of camp with a bone bruise in the repaired knee. "That didn't happen tonight for a variety of reasons and I'm my own harshest critic and I didn't feel like I played up to my potential. Count it to rest or count it to whatever it may be but I just feel like I don't make excuses whether it be I've been out for a year or I've been practicing for a week and a half. I step on the football I expect to make plays. I just felt like there were some plays I left out there today.''

On the pass that was picked off Nelson came up limping and sat on the bench for a short time. But he said it was just calf cramps.

"That's all it was'' he said. "It had been building up throughout the game. I hadn’t played in a year and I’m not making excuses by any means but it was just a lot of volume in a short amount of time and the knee felt fine.”

Despite the fact the Browns are excited about his potential particularly as a slot receiver Nelson feels he's on the bubble heading into Saturday's final cuts which are due by 6 p.m.

"To be quite honest with you I do (worry)'' he said. "I feel like I had a great week of practice I really do. I feel like I had a great week. But tonight for whatever reason whether it was slipping or whatever I just couldn't keep things in a rhythm. If I had 10 balls thrown to me I wanted to catch it 10 times. I wanted to be perfect.''

Nelson who signed a one-year deal worth $680000 including $25000 guaranteed is hoping the Browns have invested enough time in him to want to keep him around.
