Wide receiver Calvin Johnson has called for a reaction from the Detroit Lions.
The Lions suffered a a 37-27 loss to the Pittsburgh Steelers last weekend, and Johnson has insisted that they must respond positively if they are to make the NFL playoffs.
Johnson and his team currently lead the NFC North and face the Tampa Bay Buccaneers on Sunday.
'The Megatron' wrote in his weekly blog for DetroitLions.com: "We need to regain focus.
"This week is another NFC opponent, so it's a must-win for us. We've got to stack up these wins, we don't want to take two 'Ls' in a row.
"We are positive because we are still in a good position right now, still with six games to go, we still have our destiny in our hands."
Johnson has more receiving yards than anybody else in the NFL with 1,083 and is tied for a league-high 11 touchdowns with New Orleans Saints tight end Jimmy Graham.
