To cap off week 16 games in the NFL, the Indianapolis Colts will be taking on the San Francisco 49ers on Monday night. Here are five of the best player props for the game on Underdog Fantasy.

Tyler Warren Over 3.5 Receptions

In Phillip Rivers' first game back in the NFL against the Seattle Seahawks, the pass catcher he targeted the most was TE Tyler Warren. In the game Warren had three receptions for 19 yards on six targets. Over his long career, Rivers has loved passing to the TE position, and with another week did get has adjusted it feels Warren should remain involved and be able to cover the over on his 3.5 reception line.

The 49ers, in their last game against the Tennessee Titans, allowed two TEs to have four receptions. Tennessee is one of three teams that have had a TE with four or more receptions against San Francisco in their last six games.

Jonathan Taylor Over 23.5 Rush Attempts

With Rivers still at QB, RB1 for the Colts, Jonathan Taylor should still be heavily involved. Last week, against one of the best rushing defenses in the NFL, the Seahawks, Taylor had 25 carries for 87 yards. The 49ers are still a good rush defense, allowing the 12th fewest rushing yards per game, but not on the same level as Seattle, which is allowing the third fewest. With this, the Colts should not hesitate to use their superstar a large amount in this contest, making his over 23.5 rushes a great player prop to take on Monday night.

Jauan Jennings Over 55.5 Receiving Yards

With WR Ricky Pearsall out, the volume should rise for other 49ers WR Jauan Jennings. This season, Jennings has only covered the over on his Monday night 55.5 receiving yard line twice in 12 games. However, his move up to WR1 should be enough to allow him to hit the over on this line.

The Colts lately have been terrible at defending opposing WR1s. In their past five games, all opposing WR1s have covered Jennings' line, with four of them going for over 100 receiving yards.

George Kittle Over 5.5 Receptions

Again with Pearsall out, Kittle should see a slight tick up in volume. In his last five games, he has had six or more receptions four times. This is not a prop to overthink and just take the over on the 5.5 reception line. Also, with the fact that the Colts are a below-average team in guarding the TE position, as shown by this fantasy football stat.

In PPR fantasy formats, the Colts are allowing the eighth most fantasy points out of any team to the TE position.

Christian McCaffrey Under 17.5 Rush Attempts

With the god rushing defense of Indianapolis, Christian McCaffrey should not have great success in the run game. The Colts, on the season, are allowing the fourth fewest rushing yards per game in the NFL. The last time McCafrrey played a team that was in the top 10 fewest of this category, the Houston Texans, he had eight rushes for 25 yards.
