EDEN PRAIRIE, Minn. — The Vikings held their eighth organized team activity (OTA) practice on Tuesday morning at Winter Park.

The session, which was open to the media, was approximately 90 minutes outside in helmets and shorts in sunny but crisp weather.

The Vikings are scheduled to have four OTA practices this week and will hold a mandatory minicamp next week.

Here are three observations from Tuesday's session:

1. Punting practice

The Vikings added a wrinkle during offensive team drills as quarterbacks Teddy Bridgewater and Taylor Heinicke worked on their pooch punts from the 45-yard line in opponents' territory. Both quarterbacks lofted their punts to the 6-yard line, drawing loud cheers from teammates, but the duo was soon bested by kicker Blair Walsh. The Vikings lined up in field goal formation before Walsh tried a pooch punt of his own and rolled it out of bounds at the 2-yard line.

2. Nearly perfect

Walsh also shined in field goal drills in breezy conditions. The fifth-year kicker hit his first seven field goal tries, all from 32 to 45 yards out, including one from extra point distance. Although Walsh then missed from on a 48-yard try, Vikings Head Coach Mike Zimmer let him have another try. Walsh stepped up and nailed his final attempt of the day.

3. Mixing and matching

The Vikings were without cornerback Captain Munnerlyn, whose son was born Monday. As a result, cornerback Terence Newman lined up as the first-team nickel cornerback while cornerback Trae Waynes lined up as an outside cornerback along with Xavier Rhodes. Waynes, the 11th overall pick in 2015, had excellent coverage on wide receiver Charles Johnson on a deep pass along the sideline.
