The Kansas City Chiefs take on the Las Vegas Raiders and Travis Kelce will be one to watch for the visitors. The tight end has been in good form so far over the past four weeks and will be looking for another improved performance as he has been named to start.Many thought that the Chiefs' offense would struggle with the loss of Tyreek Hill as he was traded to the Miami Dolphins. Nonetheless, the Chiefs have not missed a beat, going 3-1 as they sit on top of the much-vaunted AFC West.PFF KC Chiefs@PFF_ChiefsHighest graded Chiefs in Week 4 win vs Buccaneers:🥇 Travis Kelce - 91.4🥈 Patrick Mahomes - 86.1🥉 Chris Jones - 84.9 L’Jarius Sneed - 82.0 Creed Humphrey - 81.043731Highest graded Chiefs in Week 4 win vs Buccaneers:🥇 Travis Kelce - 91.4🥈 Patrick Mahomes - 86.1🥉 Chris Jones - 84.94️⃣ L’Jarius Sneed - 82.05️⃣ Creed Humphrey - 81.0 https://t.co/DWMhtYD9H0Kelce leads the Chiefs in receiving yards with 322 and Juju Smith-Schuster is second with 224 receiving yards.

Through four games, the the 33-year-old has not been held under 50 receiving yards. That will need to happen if the Raiders have any chance of getting their second win of the season.Sunday Night Football on NBC@SNFonNBCTravis Kelce has had a monster night for #ChiefsKingdom!#NextGenStats powered by @awscloud21031Travis Kelce has had a monster night for #ChiefsKingdom!#NextGenStats powered by @awscloud https://t.co/I2DaX0iwzYIn Kelce's last five games, the tight end has ammassed 471 receiving yards from 32 catches and has two touchdowns. Before last year's second matchup in December, the tight end was on a run of three consecutive games against the Raiders, totaling over 100 yards receiving per statmuse.com. It is also worth noting that he averages a whopping 14.7 yards per catch as well.So it is clear that the Raiders defense has a problem trying to stop the 33-year-old. But it is something that they will need to do. Before their 32-23 win over the Broncos last week, the Raiders lost their opening three games of the year. A loss to the Chiefs will have them sitting at 1-4, making the playoffs a steep challenge to mount.This is not something many expected given the additions to the Las Vegas squad during the offseason. It will be a critical game in the Raiders' season, and if they are to pull off a win, Travis Kelce can't be allowed to get loose in the secondary.
