Cleveland Browns quarterback Baker Mayfield injured his throwing hand in last week's game against the Pittsburgh Steelers, but is still expected to be ready this weekend.
On Wednesday, Mayfield practiced with his right hand wrapped, but did not throw.
However, with this hand still wrapped Baker did throw during Thursday's practice according to Cleveland.com's Mary Kay Cabot.
Cabot's video hit Twitter at 11:23 a.m. ET and the betting market showed an immediate reaction.
Within five minutes, the Bengals vs. Browns over/under moved from 41 to 41.5, likely in reaction to Mayfield apparently trending in the right direction.

While a half-point move may not seem all that drastic, 41 is one of the most important numbers in NFL over/under betting, plus an ugly early forecast for this game may also be keeping that total at bay.
At the time of writing 67% of bets on the total have hit the over.
When it comes to the Bengals vs. Browns spread, bettors have been piling on the underdog.
Cincinnati has attracted 67% of spread bets, sending this line crashing from an opener of +9.5 to +7.5 across the market.
With Mayfield now looking ready to play on Sunday, it'll be interesting to monitor whether Cincy money continues to drive this down to the key number of 7, or if optimism surrounding Baker convinces Browns backers to show up and push this spread back toward the opener.
