Yahoo Fantasy X Breakingt Week 4 Shirt: Kenneth Walker Continues Breakout Season With Chiefs

Yahoo Fantasy is teaming up withBreakingT, home of the fastest-licensed fan gear in the world, to launch the Yahoo Fantasy Shirt of the Week, celebrating the one play or player that defined the fantasy week. The names on your roster are about to be the names on your chest.

BreakingT is a newsroom that happens to make shirts. Using its proprietary CrowdBreak platform, BreakingT tracks what fans are reacting to across social media in real time — surfacing the moments, memes and micro-stories that matter most to each fanbase — and its design team turns those moments into officially licensed gear in hours, not months.

How it works

Every week of the NFL season, once the Monday night game goes final, the Yahoo Fantasy team will crown the play or player that defined the fantasy week.

Some weeks it's a single snap — the 75-yard catch-and-run that decides thousands of matchups, or the goal-line plunge that flipped your week with 30 seconds left. Other weeks, it's a full-blown eruption — the four-touchdown, 200-yard game that carried a lineup on its own. Whatever it is, BreakingT turns it into a shirt, and that shirt drops.

Every Tuesday. All season long.

Now, when the fantasy week resets, you can also pick up gear that celebrates your victory and puts the rest of the league on blast.

Week 4's shirt: Beware of K9

• On an undefeated team with arguably the best QB of the past decade, Kenneth Walker has been the focal point of the Kansas City offense. Walker's 177-yard rushing performance gives him a league-leading 537 yards and he's scored multiple touchdowns in three out of four games so far. A fringe first-round pick this summer, Walker looks like a league-winning player in fantasy early on.
