Run it again. A still shot of the bill reveals a number of up-charges, including additional gratuity of $200k Duane Brown Jersey . 49ers defensive lineman Arik Armstead, who announced the pick of Jackson at the draft, took to Twitter to debunk the video.Yall silly if you thought a dinner can cost 300k . It was a prank. The waitre s went overboard . The dinner was 7500 me and 2 other vets gave 1k towards it . The rooks Russell Wilson Jersey split 4500. We had a great time too. I had good vets as a young player I would never do a rookie like that . Arik Armstead (@arikarmstead) So, there you go. It was still expensive, but the veterans helped out, and Jackson didn't have to spend all of his rookie earnings on one dinner. All's fair in San Francisco, and the chemistry seems fine, too.Those veterans, however, might want to sit Jackson down and explain posting things to social media can have consequences, no matter how silly. All Shaquill Griffin Jersey it takes is one errant story for people to wonder if the 49ers veterans are trying to make the rookies go broke.
