Friday marks the beginning of on-field testing for the six former Oregon Ducks taking part in the 2015 NFL Scouting Combine in Indianapolis, with offensive linemen Jake Fisher and Hroniss Grasu set to first take the field at Lucas Oil Stadium.

As they, along with former UO teammates Marcus Mariota, Troy Hill, Tony Washington and Arik Armstead, go through testing, The Oregonian/OregonLive will update all the results below for a one-stop shop. Not all combine invitees must take part in every drill.

The workout schedule is as follows:

Friday: OL/TE/K (Fisher and Grasu)

Saturday: QB/RB/WR (Mariota)

Sunday: DL/LB (Armstead and Washington)

Monday: DB (Hill)

Cornerback Ifo Ekpre-Olomu was also invited but is rehabbing his injured knee.

Here are the latest results, with Marcus Mariota's testing under way Saturday:

This video of Mariota overlays his 40-yard dash with Florida State's Jameis Winston, who ran a 4.97-second unofficial 40.

Marcus Mariota true to his word. He said he'd run a 4.5 40 and he did. Also had a 10-foot, 1-inch broad jump. Quite an athlete — Roy Cummings (@RCummingsFHCN) February 21, 2015

Mariota later took part in the throwing session of the combine, taking turns throwing seam routes, deep balls, and "out" patterns to the sideline. Here were some thoughts from those in attendance:

Just got back from watching the QB-WR workouts from the stands. Winston and Mariota both did a nice job. Sims and Marshall struggled — Dane Brugler (@dpbrugler) February 21, 2015

Mariota had a few overthrows, but settled in and started getting comfortable quickly. Mannion/Petty were very up-and-down w/ their accuracy — Dane Brugler (@dpbrugler) February 21, 2015

Thought Winston and Mariota both had a really strong day throwing the ball. — Daniel Jeremiah (@MoveTheSticks) February 21, 2015

Update, 1 p.m. Saturday: Cornerback Ifo Ekpre-Olomu told reporters that he could be back playing by September because his rehabilitation from a knee injury last December is ahead of schedule.

Ekpre-Olomu tore the anterior cruciate ligament in his knee during practices preceding Oregon's Jan. 1 Rose Bowl appearance against Florida State. The senior All-American had been considered a likely second-round draft choice before the injury.

CB Ifo Ekpre-Olomu on his ACL injury: “My doctor said we’re going to be looking closer to September trying to get back on the field by then" — Dane Brugler (@dpbrugler) February 21, 2015

#Oregon CB Ifo Ekpre-Olomu said everything's ahead of schedule in his rehab & he's been told by doctors he should be ready to play by Sept. — Bruce Feldman (@BruceFeldmanCFB) February 21, 2015

#Texans have had an informal meeting with Ifo Ekpre-Olomu from #Oregon. Had surgery on his ACL 8 weeks ago. — patrick (@PatDStat) February 21, 2015

Ohio State's Doran Grant, Oregon's Troy Hill, LSU's Jalen Collins, & Ole Miss' Senquez Golson all had a solid, helpful Combine from group 1. — Dion Caputi (@nfldraftupdate) February 23, 2015

Measured at 5-10, 182.

Update: 8:49 a.m., Monday: Ifo Ekpre-Olomu was interviewed by NFL Network during the cornerback field drills portion -- the drills he would have taken part in had he not torn the ACL in his knee in December -- and said his interviews have gone well at the combine.

"I feel for the most part I did a great job in the interviews so far and all the coaches were real impressed," said Ekpre-Olomu, who added he will do the bench press at Oregon's March 12 pro day but no drills as he continues to recover.

Update: 11:30 a.m., Monday: That's a wrap for the combine. Oregon's "pro day" in front of scouts is March 12.
